The aim of this study was to analyze the impact of core variations on sustained virological response (SVR) to pegylated interferon plus ribavirin (PEG-IFN/RBV) and its association with predictive factors of response in Caucasian patients infected with genotype 1 hepatitis C virus (HCV-1). Full-length core sequences were analyzed in 100 Caucasian HCV-1-infected patients who received therapy with PEG-IFN/RBV. The associations between variations in the core protein and SVR, as well as with predictors of SVR, were analyzed. Variations at core 62, 70 and 110 were selected as candidates. There were almost no variations at these positions among patients harboring HCV-1a. However, they were identified in 10 (30.3 %), 21 (63.6 %) and 13 (39.4 %) subjects with HCV-1b, respectively. Among the HCV-1b patients, 39.1 % individuals carrying core R62 and 70 % subjects with core R62G showed SVR (p = 0.141), and 66.7 % of HCV-1b patients harboring core R70 and 38.1 % with core R70Q achieved SVR (p = 0.157), whereas the rate of SVR was 70 % for individuals with core T110 and 15.4 % for those with core T110N (p = 0.004). No statistical interaction between core variations and IL28B genotype was observed. Patients with R70 showed higher median (interquartile range) baseline plasma levels of low-density-lipoprotein cholesterol (LDL-C) than those with R70Q (96 [86-118] mg/dL vs. 76 [54-88] mg/dL, p = 0.014). We concluded that a substitution at core 110 is associated with a lower rate of SVR in Caucasian HCV-1b-infected patients receiving PEG-IFN/RBV. Furthermore, the variation at the core 70 position is related to plasma levels of LDL-C in these patients. [ABSTRACT FROM AUTHOR]

Health ,Seniors - Abstract
Few studies have examined the content of individuals' goals for retirement (Hershey, Jacobs-Lawson and Neukan, 2002). In the present investigation, 184 adults between the ages of 20-64 (M=41.8 years) made four ratings for 12 different retirement goals (e.g. travel, pursuing hobbies, volunteer activities, relaxation, health maintenance). For each of the goals, individuals were asked to indicate: (a) its importance (b) how much thought and effort had been allocated toward achieving it, (c) the likelihood of achieving each goal and (d) how bad it would be if it could not be achieved. Separate factor analyses were conducted for each of the four rating dimensions across the complete set of 12 goals. All four analyses revealed support for a two-factor model that distinguished goals relevant to oneself (e.g. be happy, be healthy, be financially secure), and goals that involved others (e.g., volunteer, spend time with family members). Additional analyses failed to reveal age differences in this basic two-factor structure. These findings contribute to the formation of a content model (Austin and Vancouver, 1996) of retirement goals, which is currently lacking in the gerontological literature.

Health ,Seniors - Abstract
Research has demonstrated that financial planning for retirement is one area in which many individuals fall short of their goals. In fact, 38% of baby boomers have saved less then $10K for retirement and only 29 percent of these individuals have accumulated at least $100,000 (Stoneman, 1997). The goal of this project was to examine the psychomotivational factors that underlie individuals' decisions to save for retirement. A total of 150 particpants (79 men, 71 women) aged 25-45 years (M=34.3) completed a questionnaire that measured seven psychological constructs as well as the amount of planning and savings they had conducted. Multiple hierarchical regression analyses were used to test a nested model of retirement savings. Results provided strong support for the hypothesized model, with 45 percent of the variance explained in savings behavior, and 57 percent of the variance explained in retirement planning practices. Particularly noteworthy was the emergence of two new constructs designed to tap goal and fear based planning motives. Both were shown to be key constructs that underlie the tendency to plan and save. Major findings are discussed in terms of the implications of a holistic psychological model of savings behavior.

- Abstract
Background: Single-nucleotide polymorphisms (SNPs) near the IL28B gene have recently been associated with spontaneous hepatitis C virus (HCV) clearance and response to interferon-based therapies in patients with chronic hepatitis C. Because human immunodeficiency virus (HIV) coinfection appears to accelerate HCV-related liver fibrosis progression, any influence of IL28B SNP on the risk of developing cirrhosis might be more easily recognized in the coinfected population.Methods: All HIV-HCV-coinfected patients who underwent hepatic elastography before initiating a course of pegylated interferon plus ribavirin therapy at 2 Spanish clinics were retrospectively identified. Liver cirrhosis was defined as >14.5 kPa by transient elastography. The IL28B rs12979860 SNP was examined in a blinded fashion.Results: A total of 304 HIV-HCV-coinfected individuals were analyzed (mean age, 43 years; 80% were male; and 85% were receiving antiretroviral therapy), of whom 18% had cirrhosis. IL28B genotype distribution was as follows: CC, 46%; CT, 43%; and TT, 11%. Cirrhosis was more frequent in CC than CT/TT carriers (24% vs 13%; P = .01). Logistic regression analysis revealed that older age (odds ratio [OR], 1.05; 95% confidence interval [CI], 0.99-1.12]; P = .08), past alcohol abuse (OR, 1.97; 95% CI, 0.95-4.06; P = .07), and CC IL28B genotype (OR, 2.32; 95% CI, 1.22-4.41; P = .01) were predictors of cirrhosis. Interestingly, mean (SD) alanine aminotransferase (ALT) levels were greater (90 ± 53 vs 71 ± 33 IU/L;, P = .01) in IL28B CC than CT/TT carriers during the prior 4.8 ± 3.8 years.Conclusions: The IL28B rs12979860 CC genotype is associated with a higher prevalence of cirrhosis in HIV-HCV-coinfected patients than CT/TT genotypes, suggesting that IL28B CC carriers may experience a more rapid progression of HCV-related liver fibrosis, perhaps as result of increased liver inflammation. Thus, access to HCV treatment is of utmost importance in IL28B CC carriers, in whom treatment response is better and in whom progression to cirrhosis might occur more rapidly.

- Abstract
Background: Skin sensitivity is a common problem in the Western population correlated with changes of skin properties like skin barrier function, hydration and skin physiology. Skin properties can be modulated by dietary fatty acids (FA), especially poly-unsaturated FA. The present study was performed to evaluate the effect of daily supplementation with flaxseed oil and safflowerseed oil on healthy volunteers with sensitive skin. Methods: The study was designed as a randomized, double-blind 12-week intervention with 2 female treatment groups (n = 13). Plasma FA profile, skin sensitivity, skin hydration, transepidermal water loss (TEWL) and skin surface were evaluated on day 0, week 6 and week 12. Results: Supplementation with flaxseed oil led to significant decreases in sensitivity (after nicotinate irritation), TEWL, skin roughness and scaling, while smoothness and hydration were increased. Concomitantly, the ratio of n-6/n-3 FA in plasma decreased. Upon supplementation with safflowerseed oil, only a significant improvement in skin roughness and hydration was observed; however, the effects were less pronounced and determined at a later point in time than with flaxseed oil. The plasma n-6/n-3 FA ratio increased. Conclusion: The data provide evidence that daily intake of flaxseed oil modulates skin condition. Copyright © 2010 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Medicine - Abstract
Abstract The overall effect of HAART on the liver is the result of the balance between hepatotoxicity and the consequences of immunoreconstitution on the evolution of HIV-associated liver diseases, particularly viral hepatitis. HAART may lead to the emergence of acute toxic hepatitis, steatosis, steatohepatitis, liver fibrosis, and noncirrhotic portal hypertension. On the other hand, HAART use has been associated with slower fibrosis progression in HIV/HCV-coinfected patients in most studies dealing with this issue. As well, an improvement of the clinical outcome of liver disease has been reported in patients taking HAART. For these reasons, the short- and mid-term effects of HAART on the liver are mostly beneficial.

García., [Objective] The aim of this study was to determine the predictive capacity of response at treatment week (TW) 4 for the achievement of sustained virological response 12 weeks after the scheduled end of therapy date (SVR12) to treatment against hepatitis C virus (HCV) genotype 3 (GT3) infection with all-oral direct-acting antiviral (DAA) -based regimens., [Patients and methods] From a prospective multicohort study, HCV GT3-infected patients who completed a course of currently recommended DAA-based therapy at 33 Spanish hospitals and who had reached the SVR12 evaluation time-point were selected. TW4 HCV-RNA levels were categorized as target-not-detected (TND), below the lower limit of quantification (LLOQTD) and ≥LLOQ., [Results] A total of 123 patients were included, 86 (70%) received sofosbuvir/ daclatasvir ± ribavirin, 27 (22%) received sofosbuvir/ ledipasvir/ ribavirin and 10 (8.1%) received sofosbuvir/ ribavirin, respectively. In all, 114 (92.7%) of the 123 patients presented SVR12 in an on-treatment approach, but nine (7.3%) patients relapsed, all of them had presented cirrhosis at baseline. In those who achieved TND, LLOQTD and ≥LLOQ, SVR12 was observed in 81/83 (98%; 95% CI 91.5%–99.7%), 24/28 (85.7%; 95% CI 67.3%–96%) and 9/12 (75%; 95% CI 42.8%–94.5%), respectively; p(linear association) 0.001. Corresponding numbers for subjects with cirrhosis were: 52/54 (96.3%; 95% CI 87.3%–95.5%), 14/18 (77.8%; 95% CI 52.4%–93.6%) and 7/10 (70%; 95% CI 34.8%–93.3%); p 0.004., [Conclusions] TW4-response indicates the probability of achieving SVR12 to currently used DAA-based therapy in HCV genotype 3-infected individuals with cirrhosis. This finding may be useful to tailor treatment strategy in this setting., This work has been partially funded by the RD12/0017/0012 project as part of the Plan Nacional R+D+I and co-financed by ISCIII-Subdirección General de Evaluación, the Fondo Europeo de Desarrollo Regional (FEDER) and the Consejería de Salud of the Junta de Andalucía (grant number AC-0095-2013 and PI-0492-2012).

[Background] Acute hepatitis C virus (HCV) infection (AHCVI) outbreaks have been described recently within defined areas worldwide among HIV-infected homosexual men. This study aims to describe the cumulative frequency and incidence of firstly acquired AHCVI in an HIV-infected population in Southern Spain., [Methods] This is a retrospective study conducted at the Infectious Diseases Units of eight hospitals in Andalusia, Southern Spain. Primary AHC was considered as HCV immunoglobulin G antibody seroconversion. The time of infection was considered the moment between the last negative and the first positive HCV antibody determination., [Results] A total of 23 cases of primary AHCVI have been detected from 2000 to 2014. Incidence rates [IR; 95 % confidence interval (CI)] were 0.036 (2.272–0.054) per 100 person-years (py) in the overall population over a follow-up period of 64170 py. Of the 22 (95.7 %) male subjects, 21 (95.5 %) had acquired AHCVI by homosexual contact, the IR (95 % CI) was 0.039 (0.024–0.06) per 100 py in this subpopulation. There was no evidence of an increase of AHCVI IR. The incidence of AHCVI was slightly lower between 2000 and 2004 as compared to 2005–2009 [IR ratio (IRR) of 8.8 (95 % CI: 1.279–378.794; p = 0.01)] but reached a plateau afterwards [IRR between 2010 and 2014 versus 2005–2009: 0.727 (0.286–1.848; p = 0.5)]. The median (Q1-Q3) time between the last negative anti-HCV and the first positive anti-HCV determination was 4.7 (1.9–11.2) months. Peak (Q1-Q3) ALT and total bilirubin values during AHCVI were 496 (291–656) IU/mL and 1.15 (0.9–1.98) mg/dL, respectively., [Conclusions] In contrast to what has been reported from other areas, the incidence of primary AHCVI in the HIV-infected population is stable in Southern Spain and there is no evidence of an epidemic, in spite of the high prevalence of HIV/HCV-coinfection in this area., This work has been partially funded by the RD12/0017/0012 project as part of the Plan Nacional R + D + I and cofinanced by ISCIII-Subdirección General de Evaluación, the Fondo Europeo de Desarrollo Regional (FEDER), and the Instituto de Salud Carlos III (grant number PI15/01124).

[Objective] To assess the current frequency of ART-associated grade 3–4 transaminase elevations (TE) and grade 4 total bilirubin elevations (TBE) in HIV-infected patients with chronic hepatitis B and/or C, who start a new regimen of ART., [Patients and Methods] A total of 192 pre-treated or treatment-naive HIV infected patients with HBV and/or HCV-coinfection who started ART in eight Southern Spanish centers from July/2011-December/2013, were followed for 12 months in this prospective study., [Results] Forty-one (21.4%) subjects had been naïve to ART, median (IQR) follow-up was 11.6 (5.6–12.9) months. The most frequently initiated NRTI were tenofovir/emtricitabine [49 patients (25.5%)]. Eighty-nine (46.4%) patients started a ritonavir-boosted protease inhibitor and 77 (40.1%) individuals a NNRTI. Raltegravir and maraviroc were initiated in 24 (12.5%) and 9 (4.7%) individuals. Ten [5.21%; 95% confidence interval (CI): 2.53%-9.37%] patients presented grade 3 TE, while 8 (4.17%; 95%CI: 1.82%-8.04%) subjects showed grade 4 TBE. No episodes of grade 4 TE or ART discontinuation due to hepatotoxic events were observed. The use of ritonavir-boosted atazanavir was the only independent predictor for grade 4 TBE [adjusted odds ratio: 7.327 (95%CI: 1.417–37.89); p = 0.018] in an analysis adjusted for age, sex and baseline HIV-RNA levels, while no factor could be independently associated with grade 3–4 TE., [Conclusions] Currently, the frequency of severe ART-associated TE and TBE under real-life conditions in patients with chronic viral hepatitis is similar to what has been reported previously. However, episodes of grade 4 TE are less frequent and severe TE appears to be of lesser concern., This work was supported by the Red de Investigación en SIDA (ISCIII-RETIC RD06/006 and ISCIII-RETIC RD12/0017), the Ministerio de Sanidad y Servicios Sociales (grant number EC11-303) and the Consejería de Salud of the Junta de Andalucía (grant number AC-0095-2013).

Objectives The aim of this study was to evaluate the frequency of transaminase elevations (TE) and total bilirubin elevations (TBE) during the first year of therapy with a single tablet regimen including RPV/FTC/TDF (EPA) in HIV/hepatitis C virus (HCV)-coinfected subjects in clinical practice. Methods In a retrospective analysis, HIV/HCV-coinfected subjects who started EPA at 17 centres throughout Spain were included as cases. Subjects who started an antiretroviral therapy (ART) other than EPA during the study period at the same hospitals were randomly selected as controls in a 1:2 ratio. Primary outcome variables were grade (G) 3–4 TE and G4 TBE. Results Of the 519 subjects included, 173 individuals started EPA. Nine (5.2%) subjects of the EPA group and 49 (14.2%) controls were naive to ART. The median (Q1–Q3) follow-up was 11.2 (9.7–13.9) months. TE was observed in 2 [1.2%; 95% confidence interval (CI): 0.14%–4.1%] subjects receiving EPA and 11 (3.2%; 95%CI: 1.6%–5.6%) controls (p = 0.136), all events were G3. No patient discontinued ART due to TE. One (0.6%; 95%CI: 0.01%–3.1%) subject on EPA and 8 (2.3%; 95%CI: 1%–4.5%) subjects in the control group developed TBE (p = 0.141), without developing any other hepatic event during follow-up. Three (2.3%) subjects with cirrhosis versus 10 (3.1%) without cirrhosis showed G3-4 TE (p = 0.451). Conclusion The frequency of severe liver toxicity in HIV/HCV-coinfected subjects receiving EPA under real-life conditions is very low, TE were generally mild and did not lead to drug discontinuation. All these data suggest that EPA can be safely used in this particular subpopulation.

Journal Article; The implementation of hepatitis C (HCV) direct-acting antiviral drugs is prioritized in several populations in which its application provides the most immediate and impactful benefit. In this scenario, a precise knowledge of the situation of human immunodeficiency virus (HIV)/HCV chronic co-infection is required to adequately address this disease. This cross-sectional study was performed in 21 hospitals in Andalusia (Spain). The study population consisted of HIV-infected patients with an active HCV chronic infection who were not receiving HCV treatment at the time of inclusion. A total of 13,506 HIV-infected patients were included in the study. Of them, 2561 (18.9 %) presented chronic HCV infection. The majority of the patients included were on highly active antiretroviral therapy (HAART; 96.2 %), showed plasma levels with an undetectable HIV viral load (92.5 %), and had a good immunological status (median CD4+ cell count of 486 cells/mL). The HCV genotype distribution was as follows: 58.1 % were genotype 1, 1.1 % were genotype 2, 16.1 % were genotype 3, and 22.1 % were genotype 4 (2.6 % were missing data). In total, 24.8 % of the patients showed liver fibrosis stage F0-F1, 27.9 % showed stage F2, 16.7 % showed stage F3, and 21 % showed stage F4 (9.6 % were missing data). With regards to previous HCV treatment experiences, 68.05 % of the patients were naïve and 31.95 % had failed to respond to a previous treatment. The burden of HCV/HIV co-infected patients in our population was reported as one in five HIV-infected patients requiring HCV treatment. The implementation of extra resources to face this important health challenge is mandatory. Yes

- Abstract
BACKGROUNDWe evaluated the safety and viral rebound, after analytical treatment interruption (ATI), of vedolizumab and ART in recent HIV-1 infection. We used this model to analyze the effect of α4β7 on the HIV-1 reservoir size.METHODSParticipants started ART with monthly vedolizumab infusions, and ATI was performed at week 24. Biopsies were obtained from ileum and cecum at baseline and week 24. Vedolizumab levels, HIV-1 reservoir, flow cytometry, and cell-sorting and antibody competition experiments were assayed.RESULTSVedolizumab was safe and well tolerated. No participant achieved undetectable viremia off ART 24 weeks after ATI. Only a modest effect on the time to achieve more than 1,000 HIV-1 RNA copies/mL and the proportion of participants off ART was observed, being higher in the vedolizumab group compared with historical controls. Just before ATI, α4β7 expression was associated with HIV-1 DNA and RNA in peripheral blood and with PD1 and TIGIT levels. Importantly, a complete blocking of α4β7 was observed on peripheral CD4+ T cells but not in gut (ileum and cecum), where α4β7 blockade and vedolizumab levels were inversely associated with HIV-1 DNA.CONCLUSIONOur findings support α4β7 as an important determinant in HIV-1 reservoir size, suggesting the complete α4β7 blockade in tissue as a promising tool for HIV-cure combination strategies.TRIAL REGISTRATIONClinicalTrials.gov NCT03577782.FUNDINGThis work was supported by the Instituto de Salud Carlos III (Fondo Europeo de Desarrollo Regional, "a way to make Europe," research contracts FI17/00186 and FI19/00083 and research projects PI18/01532, PI19/01127, PI22/01796), Conserjería de Economía, Conocimiento, Empresas y Universidad, Junta de Andalucía (research projects P20/00906), the Red Temática de Investigación Cooperativa en SIDA (RD16/0025/0020), and the Spanish National Research Council.

- Abstract
Background and Aim: Dialysis patients are a high-risk population and have a reduced immune response to vaccination against SARS-CoV-2. The aim of this study was to assess the humoral response to homologous Gam-COVID-Vac (Sputnik V) and heterologous Sputnik V/mRNA-1273 (Moderna) vaccination in dialysis patients. The vaccination scheme depended on dose availability and the prioritization of risk populations as established by the Argentine Ministry of Health., Methods: Previous COVID-19 infection was determined in symptomatic patients. Binding IgG antibodies against the spike (S) receptor-binding domain (RBD) of SARS-CoV-2 (anti-S-RBD) concentration was assessed between 3 and 16 weeks after the boost dose. Anti-S-RBD antibodies were quantified using the Abbott Diagnostics SARS-CoV-2 IgG II Quant chemiluminescent microparticle immunoassay (CMIA) on an Architect i2000 SR and an Alinity I analyzer (Abbott Diagnostics, Abbott Park, Illinois, USA). To standardize the results to WHO binding antibody units (BAU), a correction factor for Abbott arbitrary units (AU) was applied where 1 BAU/mL equals 0.142 AU, as previously established by Abbott with the WHO international standard NIBSC 20-136. Following the manufacturer's recommendations, samples were considered reactive for anti-S-RBD when titers were above 50 AU/mL (7.2 BAU/mL). An 80% protective effect (PROT-80) against symptomatic SARS-CoV-2 infection was assumed when anti-S-RBD titers were 506 BAU/ml or higher. Charlson Comorbidity Index (CCI) score was classified as mild = 1-2, moderate = 3-4, and severe ≥ 5. Side effects were evaluated until day 7 by patients´ self-reported questionnaire., Results: One hundred seven participants were enrolled [n = 84 homologous (SpV/SpV), nn 23 heterologous (SpV/Mod)]. Median (IQR) age was 64 (50-75) years old and 79 (73.8%) were male. Additionally, 19 (22.6%) of the SpV/SpV and 4 (17.4%) of the SpV/Mod group had a prior confirmed SARS-CoV-2 infection (p = 0.589). In the overall population, 103 patients reached seroconversion (96.3%). Anti-S-RBD IgG median titers (IQR) were higher in the heterologous [1222 (288-5680) BAU/mL] than in the homologous scheme [447 (100-1551) BAU/mL], p = 0.022. In a linear model adjusted for age, gender, days from first vaccination to boost dose and days from the boost dose to the anti-S-RBD IgG determination, previous SARS-COV-2 infection (B: 2062.2; CI95: 1231.8-2892.6; p < 0.001), and SpV/Mod vaccination scheme (B: 1294.6; CI95: 435.58-2147.6; p = 0.003) were independently associated with anti-S-RBD levels. Finally, a higher frequency of adverse effects was associated with the heterologous scheme, although they were well tolerated by all individuals., Conclusions: The present study provides evidence that the homologous SpV/SpV and heterologous SpV/Mod schemes showed good efficacy and safety in patients on chronic dialysis. These results could be useful for designing future vaccination strategies, especially aimed at this risk group., (© 2022. The Author(s) under exclusive licence to Italian Society of Nephrology.)

- Abstract
Background: Understanding the natural history of anal high-risk human papillomavirus (hrHPV) infection is key for designing anal cancer prevention programs but has not been systematically characterized., Methods: We reanalyzed data from 34 studies including 16 164 individuals in 6 risk groups defined by human immunodeficiency virus (HIV) status, sex, and male sexuality: men who have sex with men (MSM) and people with HIV (MSMWH), HIV-negative MSM, women with HIV (WWH), HIV-negative women, men who have sex with women (MSW) with HIV (MSWWH), and HIV-negative MSW. We used Markov models to estimate incidence and clearance of 13 hrHPV types and their determinants., Results: Human papillomavirus (HPV) 16 had the highest incidence-clearance ratio of the hrHPV types. MSMWH had the highest hrHPV incidence (eg, 15.5% newly HPV-16 infected within 2 years), followed by HIV-negative MSM (7.5%), WWH (6.6%), HIV-negative women (2.9%), MSWWH (1.7%), and HIV-negative MSW (0.7%). Determinants of HPV-16 incidence included HIV status and number of sexual partners for MSM, women, and MSW, and anal sex behavior for MSM only. HPV-16 clearance was lower for people with HIV (PWH) and lower for prevalent than incident infection. Among MSM, increasing age was associated with lower clearance of prevalent, but not incident, HPV-16 infection., Conclusions: This robust and unifying analysis of anal hrHPV natural history is essential to designing and predicting the impact of HPV vaccination and HPV-based screening programs on anal cancer prevention, particularly in MSM and PWH. Importantly, it demonstrates the higher carcinogenic potential of longstanding anal prevalent hrHPV infection than more recent incident infection., Competing Interests: Potential conflicts of interest.

- Abstract
Background: Management of the coronavirus disease 2019 (COVID-19) pandemic caused by a novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) requires rapid and simple methods to detect COVID-19 patients and identify potential infectors. This study aimed to evaluate the utility of a point-of-care (PoC) rapid antigen diagnostic test (Ag-RDT) in these settings., Patients and Methods: Individuals who consecutively presented for SARS-CoV-2 testing at a tertiary care center in Buenos Aires, Argentina, underwent PoC Ag-RDT testing and real-time RT-PCR (qRT-PCR) on the same day during June 2021., Results: Of 584 included subjects, 108 (18.5%) were symptomatic for COVID-19 while the remaining presented for miscellaneous reasons unrelated to possible or confirmed contact with a SARS-CoV-2-infected individual. A positive Ag-RDT result was obtained in 26 (24.1%) symptomatic and 7 (1.5%) asymptomatic persons ( p < 0.001), which was concordant with qRT-PCR in 105/108 [97.2%, Cohen's kappa coefficient (κ) = 0.927] symptomatic and 467/476 (98.1% κ = 0.563) asymptomatic participants, with a positive percentage agreement (PPA; 95% confidence interval) of 89.7% (71.5-97.3%) and 42.9% (18.8-70.4%), respectively. None of the 11 false-negative diagnoses showed a C
t -value ≤20. Considering only failures with a Ct -value below 31 as hypothetical infectivity threshold of 105 SARS-CoV-2 RNA copies/mL, concordance was observed in 98.1% (κ = 0.746) in the asymptomatic population, accounting for a PPA of 66.7% (30.9-91%)., Conclusions: PoC Ag-RDT accurately detected active SARS-CoV-2 infection and showed acceptable diagnostic performance in asymptomatic persons potentially spreading infectious virus. Ag-RDT may therefore be useful to slow down or stop transmission by enabling adequate decisions on isolation at a public health level., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Neukam, Lucero, Gutiérrez-Valencia, Amaya, Echegoyen, Martelli, Videla, Di Lello and Martínez.)- Published

- Abstract
Objectives: To compare the homologous prime-boost vaccination scheme of Gam-COVID-Vac (Sputnik V (SpV)) to its heterologous combination with mRNA-1273 (Moderna (Mod)) vaccine., Methods: SARS-CoV-2 anti-spike (S)-receptor binding domain (RBD) IgG concentration was assessed three to seven weeks after complete vaccination. Reactogenicity was evaluated by declared side events and medical assistance required until day 7 post boost., Results: Of 190 participants enrolled, 105 received homologous SpV/SpV and the remaining heterologous SpV/Mod vaccination scheme, respectively. Median (interquartile range (IQR)) age was 54 (37-63) years, 132 out of 190 (69.5%) were female, and 46 out of 190 (24.2%) individuals had a prior confirmed COVID-19. Anti-S-RBD IgG median (IQR) titers were significantly higher for SpV/Mod (2511 (1476-3992) binding antibody units (BAU)/mL) than for SpV/SpV (582 (209-1609) BAU/mL; p < 0.001] vaccination scheme. In a linear model adjusted for age, gender, time to the serological assay, and time between doses, SpV/Mod (4.154 (6.585-615.554); p < 0.001] and prior COVID (3.732 (8.641-202.010); p < 0.001) were independently associated with higher anti-S-RBD IgG values. A higher frequency of mild and moderate adverse effects was associated with the heterologous scheme (20 of 85 (23.5%) vs. 13 of 105 (12.4%); p = 0.043 and 27 of 85 (31.8%) vs. 14 of 105 (13.3%); p = 0.002), respectively, although it was well tolerated by all individuals and no medical assistance was required., Discussion: The heterologous SpV/Mod combination against SARS-CoV-2 is well tolerated and significantly increases humoral immune response as compared to the homologous SpV/SpV immunization., (Copyright © 2022 European Society of Clinical Microbiology and Infectious Diseases.

- Abstract
Background: Anal squamous cell carcinoma is rare, in general, but considerably higher in HIV-infected men who have sex with men. There is no consensus on the screening of at-risk populations., Objective: This study aimed to determine the incidence rates of anal squamous cell carcinoma and the efficacy of a screening program., Design: This is a cohort study (SeVIHanal/NCT03713229)., Setting: This study was conducted at an HIV outpatient clinic in Seville, Spain., Patients: From 2004 to 2017, all patients with at least 1 follow-up visit were analyzed (follow-up group), including a subgroup of men who have sex with men who participated in a specialized program for screening and treating anal neoplasia (SCAN group) from 2011 onward., Main Outcome Measures: The primary outcome measure was the incidence rate of anal squamous cell carcinoma., Results: Of the 3878 people living with HIV included in the follow-up group, 897 were transferred to the SCAN group; 1584 (41%) were men who have sex with men. Total follow-up was 29,228 person-years with an overall incidence rate for anal squamous cell carcinoma of 68.4/100,000 person-years (95% CI, 46.7-97.4). The changes in the incidence rate/100,000 person-years (95% CI) over time was 20.7 (3.40-80.5) for 2004 to 2006, 37.3 (13.4-87.3) for 2007 to 2010, and 97.8 (63.8-144.9) for 2011 to 2017 (p < 0.001). The strongest impact on the incidence of anal squamous cell carcinoma was made by the lack of immune restoration (adjusted incidence rate ratio (95% CI): 6.59 (4.24-10); p < 0.001), the Centers for Disease Control and Prevention category C (adjusted incidence rate ratio (95% CI): 7.49 (5.69-9.85); p < 0.001), and non-men who have sex with men (adjusted incidence rate ratio (95% CI): 0.07 (0.05-0.10); p < 0.001) in a Poisson analysis. From 2010 to 2017, incidence rates (95% CI) of anal squamous cell carcinoma within the SCAN group and the men who have sex with men of the follow-up group were 95.7 (39.6-202) and 201 (101-386)/100,000 person-years (adjusted incidence rate ratio (95% CI): 0.30 (0.23-0.39); p<0.001). The incidence rate ratio (95% CI) including non-men who have sex with men in the follow-up group was 0.87 (0.69-1.11); p = 0.269., Limitations: Adherence to the visits could not be quantified., Conclusion: Incidence rates of anal squamous cell carcinoma in people living with HIV increased significantly from 2004 to 2017, especially in men who have sex with men who were not being screened. Participation in the SCAN program significantly reduced the incidence of anal squamous cell carcinoma in men who have sex with men, in whom focus should be placed, especially on those presenting with Centers for Disease Control and Prevention category C and advanced immune suppression.

No hay consenso sobre el cribado de poblaciones en riesgo.OBJETIVO:Este estudio tuvo como objetivo determinar las tasas de incidencia del carcinoma anal a células escamosas y la eficacia de un programa de detección.DISEÑO:Estudio de cohorte (SeVIHanal / NCT03713229).AJUSTE:Clínica ambulatoria de VIH en Sevilla, España.PACIENTES:De 2004 a 2017, se analizaron todos los pacientes con al menos una visita de seguimiento (grupo F / U), incluido un subgrupo de hombres que tenían relaciones sexuales con hombres que participaron en un programa especializado de cribado y tratamiento de neoplasias anales (SCAN-group) a partir de 2011.PRINCIPALES MEDIDAS DE RESULTADO:Tasas de incidencia del carcinoma anal a células escamosas.RESULTADOS:De las 3878 personas que viven con el VIH incluidas en el grupo F / U, 897 fueron transferidas al grupo SCAN, 1584 (41%) eran hombres que tenían relaciones sexuales con hombres. El seguimiento total fue de 29228 personas-año con una tasa de incidencia general de carcinoma anal a células escamosas de 68,4 / 100000 personas-año [intervalo de confianza del 95%: 46,7-97,4]. El cambio en las tasas de incidencia / 100000 personas-año (intervalo de confianza del 95%) a lo largo del tiempo fue 20,7 (3,40-80,5) para 2004-2006, 37,3 (13,4-87,3) para 2007-2010 y 97,8 (63,8-144,9) para 2011-2017, p <0,001. El impacto más fuerte en la incidencia del carcinoma a células escamosas anal fue la falta de restauración inmunológica [índice de tasa de incidencia ajustado (intervalo de confianza del 95%): 6,59 (4,24-10); p <0,001], categoría C de los Centros de Control de Enfermedades [índice de tasa de incidencia ajustado (intervalo de confianza del 95%): 7,49 (5,69-9,85); p <0,001] y no hombres que tenían relaciones sexuales con hombres [razón de tasa de incidencia ajustada (intervalo de confianza del 95%): 0,07 (0,05-0,10); p <0,001] en el análisis de Poisson. Desde 2010-2017, las tasas de incidencia (intervalo de confianza del 95%) de carcinoma anal a células escamosas dentro del grupo SCAN y los hombres que tienen relaciones sexuales con hombres del grupo F / U fueron 95,7 (39,6-202) y 201 (101- 386) / 100000 personas-año [razón de tasa de incidencia ajustada (intervalo de confianza del 95%): 0,30 (0,23-0,39); p <0,001]. La razón de la tasa de incidencia (intervalo de confianza del 95%), incluidos los no hombres que tenían relaciones sexuales con hombres en F / U, fue de 0,87 [0,69-1,11); p = 0,269].LIMITACIONES:No se pudo cuantificar la adherencia a las visitas.CONCLUSIÓNES:La tasa de incidencia del carcinoma anal a células escamosas en personas que viven con el VIH aumentó significativamente de 2004 a 2017, especialmente en hombres que tenían relaciones sexuales con hombres que no se someten a pruebas de detección. La participación en el programa SCAN redujo significativamente la incidencia de carcinoma anal a células escamosas en hombres que tenían relaciones sexuales con hombres, en quienes se debe prestar una especial atención, sobre todo en aquellos que se presentan en la categoría C de los Centros de Control de Enfermedades con inmunodeficiencia avanzada.

- Abstract
Background: Robust age-specific estimates of anal human papillomavirus (HPV) and high-grade squamous intraepithelial lesions (HSIL) in men can inform anal cancer prevention efforts. We aimed to evaluate the age-specific prevalence of anal HPV, HSIL, and their combination, in men, stratified by HIV status and sexuality., Methods: We did a systematic review for studies on anal HPV infection in men and a pooled analysis of individual-level data from eligible studies across four groups: HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive men who have sex with women (MSW), and HIV-negative MSW. Studies were required to inform on type-specific HPV infection (at least HPV16), detected by use of a PCR-based test from anal swabs, HIV status, sexuality (MSM, including those who have sex with men only or also with women, or MSW), and age. Authors of eligible studies with a sample size of 200 participants or more were invited to share deidentified individual-level data on the above four variables. Authors of studies including 40 or more HIV-positive MSW or 40 or more men from Africa (irrespective of HIV status and sexuality) were also invited to share these data. Pooled estimates of anal high-risk HPV (HR-HPV, including HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68), and HSIL or worse (HSIL+), were compared by use of adjusted prevalence ratios (aPRs) from generalised linear models., Findings: The systematic review identified 93 eligible studies, of which 64 contributed data on 29 900 men to the pooled analysis. Among HIV-negative MSW anal HPV16 prevalence was 1·8% (91 of 5190) and HR-HPV prevalence was 6·9% (345 of 5003); among HIV-positive MSW the prevalences were 8·7% (59 of 682) and 26·9% (179 of 666); among HIV-negative MSM they were 13·7% (1455 of 10 617) and 41·2% (3798 of 9215), and among HIV-positive MSM 28·5% (3819 of 13 411) and 74·3% (8765 of 11 803). In HIV-positive MSM, HPV16 prevalence was 5·6% (two of 36) among those age 15-18 years and 28·8% (141 of 490) among those age 23-24 years (p
trend =0·0091); prevalence was 31·7% (1057 of 3337) among those age 25-34 years and 22·8% (451 of 1979) among those age 55 and older (ptrend <0·0001). HPV16 prevalence in HIV-negative MSM was 6·7% (15 of 223) among those age 15-18 and 13·9% (166 of 1192) among those age 23-24 years (ptrend =0·0076); the prevalence plateaued thereafter (ptrend =0·72). Similar age-specific patterns were observed for HR-HPV. No significant differences for HPV16 or HR-HPV were found by age for either HIV-positive or HIV-negative MSW. HSIL+ detection ranged from 7·5% (12 of 160) to 54·5% (61 of 112) in HIV-positive MSM; after adjustment for heterogeneity, HIV was a significant predictor of HSIL+ (aPR 1·54, 95% CI 1·36-1·73), HPV16-positive HSIL+ (1·66, 1·36-2·03), and HSIL+ in HPV16-positive MSM (1·19, 1·04-1·37). Among HPV16-positive MSM, HSIL+ prevalence increased with age., Interpretation: High anal HPV prevalence among young HIV-positive and HIV-negative MSM highlights the benefits of gender-neutral HPV vaccination before sexual activity over catch-up vaccination. HIV-positive MSM are a priority for anal cancer screening research and initiatives targeting HPV16-positive HSIL+., Funding: International Agency for Research on Cancer., Competing Interests: Declaration of interests ARG received travel fees from Merck & Co to participate in scientific advisory board meetings, and her institution has received grants for research from Merck & Co.

- Abstract
Background: Screening methods for anal squamous intraepithelial lesions (SILs) are suboptimal. We aimed to determine the diagnostic performance of a composite endpoint comprising anal liquid-based cytology (aLBC) and high-risk human papillomavirus (HR-HPV) testing to predict histological high-grade SILs (hHSILs)., Methods: From the SeVIHanal cohort, human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) who had an aLBC with concomitant HR-HPV testing were included. hHSILs were determined by high-resolution anoscopy (HRA)-guided biopsy., Results: A total of 705 visits obtained from 426 patients were included. The prevalence of HR-HPV among aLBC results were 51.9% (133/215) normal, 87.9% (20/232) low-grade SILs (LSILs), and 90.9% (149/164) high-grade SILs; P (linear association) < .001. Low prevalence of hHSILs was only observed for the composite aLBC/HR-HPV testing endpoint "normal/noHR-HPV" (10%) and "LSIL/noHR-HPV" (4%). The prognostic values (95% confidence interval) for HR-HPV to predict hHSILs in normal cytology were positive predictive value (PPV), 29.3% (25.6%-33.3%); negative predictive value (NPV), 90.2% (82.8%-94.7%); sensitivity, 83% (69.2%-92.4%); and specificity, 44.1% (36.4%-51.9%). Corresponding figures for cytologic LSILs were PPV, 39.2% (37.4%-41.1%); NPV, 96.4% (78.9%-99.5%); sensitivity, 98.8% (93.3%-99.9%); and specificity, 17.9% (12.1%-24.9%). A positive interaction and a synergistic effect for the composite endpoint were observed (relative excess risk = 1.50, attributable proportion of histological results to interaction = 0.17, synergy index = 1.24)., Conclusions: HRA should not be indicated in the setting of LSILs/noHR-HPV following aLBC-based screening. In contrast, HIV-infected MSM with normal aLBC/HR-HPV infection should be considered for HRA., Clinical Trials Registration: NCT03713229., (© The Author(s) 2019.

- Abstract
Direct acting antiviral (DAA) therapy against hepatitis C virus (HCV) increases sustained virologic response rates. Nevertheless, drug resistance has occasionally been associated with failure to DAA. However, the information about the prevalence of NS5A and NS5B resistance-associated substitutions (RASs) in Argentina is very scarce. In this study, we determine the prevalence of NS5A and NS5B resistances to treatment in Argentinean DAA treatment-naïve patients chronically infected with genotype 1 (HCV-1). In this retrospective cross-sectional study, 108 HCV-1-infected patients were studied. RASs in NS5A and NS5B were analyzed by Sanger at baseline and phylogenetic analysis was performed. NS5A and NS5B RASs were detected in 25.8% and 6.3% of the analyzed sequences, respectively. The most frequent primary RASs for NS5A were L31M (7.5%) and Y93H (3.2%) and for NS5B was L159F (3.8%). No association between the presence of RASs and the outcome of DAA treatment was found in this study. Additionally, most of the Argentinean samples were randomly distributed among sequences around the world in the phylogenetic analysis. Only one significant Argentinean cluster was observed in both regions but without any particular RASs pattern. Baseline RASs in NS5A and NS5B were frequently observed in HCV-1-infected patients from Buenos Aires, Argentina but not related to treatment outcome. No clusters related to RASs transmission were observed in the phylogenetic analysis. The frequency of RASs detected in this study supports the need for more molecular epidemiology studies on RASs to adjust local treatment guidelines with the incorporation of autochthonous data., (© 2019 Wiley Periodicals, Inc.)

- Abstract
Objective: To determine the required learning time for high-resolution anoscopy (HRA)-guided biopsy to detect histological high-risk squamous intraepithelial lesions (hHSIL) and to identify factors that impact on the training process., Methods: All HIV-infected, screening-naïve men-who-have-sex-with-men who underwent HRA conducted by one single observer from 2010 to 2017 in a Spanish HIV-outpatient clinic were analysed., Results: Eighty-five (14.7%) of the 581 patients included presented hHSIL. The factors associated with the capacity to detect hHSIL [adjusted odds ratio (aOR), 95% confidence interval (95%CI)] were the presence of cytological HSIL (3.04, 1.78-5.21; p < 0.001), infection with high-risk human papilloma virus (HR-HPV) (2.89, 1.38-6.05; p = 0.005), the number of biopsies taken/HRA (aOR: 1.28, 1.07-1.52; p = 0.006) and tobacco smoking (1.75; 1.12-2.73; p = 0.014). Two events independently augmented the detection rate of hHSIL: one single experienced pathologist interpreted biopsies after 409 HRA (2.80, 1.74-4.48; p = 0.035) and the anoscopist underwent an additional training after 536 HRA (2.57, 1.07-6.16; p = 0.035). A learning process could be observed throughout the whole study with stable HR-HPV prevalence., Conclusion: The data support the growing evidence that the proposed training volume of 50-200 performances is underestimated. Extensive training of both anoscopist and pathologist is warranted and the development of tools to support the diagnostic performance may be considered., (Copyright © 2019 The Authors.

- Abstract
Background: HIV-infected patients are at risk of hepatitis B virus (HBV) coinfection, however, respond worse to HBV vaccination (HBV-V) than immunocompetent adults. This study aimed to determine the response to reinforced HBV-V in HIV-infected subjects under real-life conditions., Methods: HIV-infected patients followed at a Spanish University Hospital who were seronegative for HBV and who received three double-doses (40 µL) of HBV-V at 0, 1 and 2 months were included. Response to HBV-V was defined as HBV surface antibody concentration of ≥10 IU/L 1-12 months after the last HBV-V dose., Results: Of 332 patients included in the study, 256 (77.1%) showed response to HBV-V. Median (interquartile range) CD4
+ /CD8+ ratio among the responders was 0.75 (0.52-1.01) versus 0.61 (0.38-0.84) among the non-responders (p = 0.002). Independent predictors for HBV-V response were: female gender [adjusted odds ratio (AOR): 6.240; 95% confidence interval (95%CI): 1.954-19.925; p = 0.002]; non-smoking [AOR: 2.151; 95%CI: 1.243-3.721; p = 0.006]; a CD4+ /CD8+ ratio ≥0.67 [AOR: 2.580; 95%CI: 1.209-5.505; p = 0.014] and baseline HIV-RNA ≤50 copies/mL [AOR: 2.049; 95%CI: 1.098-3.824; p = 0.024]., Conclusion: Accelerated administration of three double-doses results in considerable high, however still suboptimal, response rates to HBV-V in HIV-infected patients in the clinical practice. A fourth dose should be considered., (Copyright © 2019. Published by Elsevier Ltd.)- Published

- Abstract
Background: Various recent outbreaks of hepatitis A virus (HAV) have been described in men who have sex with men despite the availability of an effective vaccine. This study aimed to determine the current rates of seroconversion after receiving HAV vaccine (HAV-V) in HIV-infected patients under real-life conditions., Setting: Patients were selected from a Southern Spanish multicentric cohort of HIV-infected subjects., Methods: Retrospective analysis of all patients who received 2 doses (standard scheme) from April 2008 to May 2016 or from June 2016 to February 2018 facing an HAV outbreak with shortage of HAV-V, 1 single dose of HAV-V. Response to HAV-V was defined as positive anti-HAV IgG between 1 and 12 months after the last vaccination dose., Results: A total of 522 patients were included, mainly men who have sex with men (86.2%). In the standard-dose group, 303/343 [88.3%; 95% confidence interval (CI): 84.5 to 91.5] patients showed seroconversion as compared with 149/179 (83.2%; 95% CI: 76.9 to 88.4) of the single-dose group (P = 0.107). Undetectable baseline HIV-RNA (adjusted odds ratio: 4.86; 95% CI: 1.86 to 12.75; P = 0.001) and a CD4 T-cell count ≥350/μL (adjusted odds ratio, 3.96; 95% CI: 1.26 to 12.49; P = 0.019) were independently associated with response to both regimens. A higher CD4/CD8 ratio was also associated with response after a single dose., Conclusions: HIV-infected patients should be encouraged to undergo HAV-V with 2 standard doses 6 months apart; a single dose achieves a high rate of seroconversion in those patients with favorable response factors and may be enough to limit future outbreaks in case of HAV-V shortage until supply is reestablished.

- Abstract
Objective: To evaluate the use of hepatitis C virus (HCV) NS3 sequencing as alternative to the comercially available Versant HCV 2.0 reverse hybridization line-probe assay (LiPA 2.0) to determine HCV genotype 1 (HCV-1) subtypes., Patients and Methods: A cohort of 104 patients infected by HCV-1 according to LiPA 2.0 was analyzed in a cross-sectional study conducted in patients seen from January 2012 to June 2016 at an outpatient clinic in Buenos Aires, Argentina., Results: The samples were included within well supported subtype clades: 64 with HCV-1b and 39 with HCV-1a infection. Twenty of the HCV-1a infected patientes were included in a supported sub-clade "1" and 19 individuals were among the basal sub-clade "2". LiPA 2.0 failed to subtype HCV-1 in 20 (19.2%) individuals. Subtype classification determined by NS3 direct sequencing showed that 2/18 (11.1%) of the HCV-1a-infected patients as determined by LiPA 2.0 were in fact infected by HCV-1b. Of the HCV-1b-infected according to LiPA 2.0, 10/66 (15.2%) patients showed HCV-1a infection according to NS3 sequencing. Overall misclassification was 14.3% (κ-index for the concordance with NS3 sequencing = 0.635). One (1%) patient was erroneously genotyped as HCV-1 and was revealed as HCV genotype 4 infection., Conclusions: Genomic sequencing of the HCV NS3 region represents an adequate alternative since it provides reliable genetic information. It even distinguishes between HCV-1a clades related to resistance-associated substitutions to HCV protease inhibitors, it provides reliable genetic information for genotyping/subgenotyping and simultaneously allows to determine the presence of resistance-associated substitutions to currently recommended DAAs.

- Abstract
Objective: HIV/HCV-coinfected patients and hepatitis C virus (HCV) monoinfected subjects are thought to respond equally to direct-acting antiviral (DAA)-based therapy despite the lack of data derived from clinical trials. This study is aimed to evaluate the impact of HIV coinfection on the response to DAA-based treatment against HCV infection in the clinical practice., Patients and Methods: In a prospective multicohort study, patients who initiated DAA-based therapy at the Infectious Disease Units of 33 hospitals throughout Spain were included. The primary efficacy outcome variables were the achievement of sustained virologic response 12 weeks after the scheduled end of therapy date (SVR12)., Results: A total of 908 individuals had reached the SVR12 evaluation time-point, 426 (46.9%) were HIV/HCV-coinfected, and 472 (52%) received interferon (IFN)-free therapy. In an intention-to-treat analysis, SVR12 rates in subjects with and without HIV-coinfection were 55.3% (94/170 patients) versus 67.3% (179/266 subjects; p = 0.012) for IFN-based treatment and 86.3% (221/256 subjects) versus 94.9% (205/216 patients, p = 0.002) for IFN-free regimens. Relapse after end-of-treatment response to IFN-free therapy was observed in 3/208 (1.4%) HCV-monoinfected subjects and 10/231 (4.4%) HIV/HCV-coinfected individuals (p = 0.075). In a multivariate analysis adjusted for age, sex, transmission route, body-mass index, HCV genotype, and cirrhosis, the absence of HIV-coinfection (adjusted odds ratio: 3.367; 95% confidence interval: 1.15-9.854; p = 0.027) was independently associated with SVR12 to IFN-free therapy., Conclusions: HIV-coinfection is associated with worse response to DAA-based therapy against HCV infection. In patients receiving IFN-free therapy, this fact seems to be mainly driven by a higher rate of relapses among HIV-coinfected subjects.

- Abstract
Background: The drug options and strategies for treatment against hepatitis C virus (HCV) infection have changed considerably in the last few years. The aim of this study was to compare the changes in the proportion of nonresponders and patients who achieved a sustained virologic response (SVR) from 1999 to 2015 in one single cohort., Patients and Methods: A total of 522 patients treated against chronic hepatitis C were included prospectively. The time periods were 1999-2002 [interferon (IFN)/ribavirin (RBV)], 2002-2009 (pegylated-IFN/RBV), 2010-2011 (use of IL28B genotype), 2012-2014 (pegylated-IFN/RBV/direct-acting antivirals) and 2015 (IFN-free direct-acting antiviral-based therapy)., Results: The numbers of nonresponders in the study periods in chronological order were as follows: 14 (40%), 76 (21.3%), 7 (8%), 10 (13%), and 0; P=1.1×10 and r=0.837. The corresponding numbers of patients who achieved SVR were 9 (25.7%), 14 (40.9%), 44 (50.6%), 51 (66.2%), and 64 (90.1%), P=3.3×10 and r=0.997. Characteristics that may impair SVR, such as advanced fibrosis, genotype 1 infection, HIV coinfection, or treatment experience, did not decrease in the last time periods., Conclusion: The proportion of nonresponders was significantly reduced using the IL28B genotype as a predictive tool and direct-acting antivirals further improved treatment outcome. Concomitantly, the rates of SVR showed a linear increase.

Background: Acute hepatitis C virus (HCV) infection (AHCVI) outbreaks have been described recently within defined areas worldwide among HIV-infected homosexual men. This study aims to describe the cumulative frequency and incidence of firstly acquired AHCVI in an HIV-infected population in Southern Spain., Methods: This is a retrospective study conducted at the Infectious Diseases Units of eight hospitals in Andalusia, Southern Spain. Primary AHC was considered as HCV immunoglobulin G antibody seroconversion. The time of infection was considered the moment between the last negative and the first positive HCV antibody determination., Results: A total of 23 cases of primary AHCVI have been detected from 2000 to 2014. Incidence rates [IR; 95 % confidence interval (CI)] were 0.036 (2.272-0.054) per 100 person-years (py) in the overall population over a follow-up period of 64170 py. Of the 22 (95.7 %) male subjects, 21 (95.5 %) had acquired AHCVI by homosexual contact, the IR (95 % CI) was 0.039 (0.024-0.06) per 100 py in this subpopulation. There was no evidence of an increase of AHCVI IR. The incidence of AHCVI was slightly lower between 2000 and 2004 as compared to 2005-2009 [IR ratio (IRR) of 8.8 (95 % CI: 1.279-378.794; p = 0.01)] but reached a plateau afterwards [IRR between 2010 and 2014 versus 2005-2009: 0.727 (0.286-1.848; p = 0.5)]. The median (Q1-Q3) time between the last negative anti-HCV and the first positive anti-HCV determination was 4.7 (1.9-11.2) months. Peak (Q1-Q3) ALT and total bilirubin values during AHCVI were 496 (291-656) IU/mL and 1.15 (0.9-1.98) mg/dL, respectively., Conclusions: In contrast to what has been reported from other areas, the incidence of primary AHCVI in the HIV-infected population is stable in Southern Spain and there is no evidence of an epidemic, in spite of the high prevalence of HIV/HCV-coinfection in this area.

- Abstract
Objectives: The aim of this study was to evaluate the frequency of transaminase elevations (TE) and total bilirubin elevations (TBE) during the first year of therapy with a single tablet regimen including RPV/FTC/TDF (EPA) in HIV/hepatitis C virus (HCV)-coinfected subjects in clinical practice., Methods: In a retrospective analysis, HIV/HCV-coinfected subjects who started EPA at 17 centres throughout Spain were included as cases. Subjects who started an antiretroviral therapy (ART) other than EPA during the study period at the same hospitals were randomly selected as controls in a 1:2 ratio. Primary outcome variables were grade (G) 3-4 TE and G4 TBE., Results: Of the 519 subjects included, 173 individuals started EPA. Nine (5.2%) subjects of the EPA group and 49 (14.2%) controls were naïve to ART. The median (Q1-Q3) follow-up was 11.2 (9.7-13.9) months. TE was observed in 2 [1.2%; 95% confidence interval (CI): 0.14%-4.1%] subjects receiving EPA and 11 (3.2%; 95%CI: 1.6%-5.6%) controls (p = 0.136), all events were G3. No patient discontinued ART due to TE. One (0.6%; 95%CI: 0.01%-3.1%) subject on EPA and 8 (2.3%; 95%CI: 1%-4.5%) subjects in the control group developed TBE (p = 0.141), without developing any other hepatic event during follow-up. Three (2.3%) subjects with cirrhosis versus 10 (3.1%) without cirrhosis showed G3-4 TE (p = 0.451)., Conclusion: The frequency of severe liver toxicity in HIV/HCV-coinfected subjects receiving EPA under real-life conditions is very low, TE were generally mild and did not lead to drug discontinuation. All these data suggest that EPA can be safely used in this particular subpopulation.

- Abstract
Objective: To assess the current frequency of ART-associated grade 3-4 transaminase elevations (TE) and grade 4 total bilirubin elevations (TBE) in HIV-infected patients with chronic hepatitis B and/or C, who start a new regimen of ART., Patients and Methods: A total of 192 pre-treated or treatment-naive HIV infected patients with HBV and/or HCV-coinfection who started ART in eight Southern Spanish centers from July/2011-December/2013, were followed for 12 months in this prospective study., Results: Forty-one (21.4%) subjects had been naïve to ART, median (IQR) follow-up was 11.6 (5.6-12.9) months. The most frequently initiated NRTI were tenofovir/emtricitabine [49 patients (25.5%)]. Eighty-nine (46.4%) patients started a ritonavir-boosted protease inhibitor and 77 (40.1%) individuals a NNRTI. Raltegravir and maraviroc were initiated in 24 (12.5%) and 9 (4.7%) individuals. Ten [5.21%; 95% confidence interval (CI): 2.53%-9.37%] patients presented grade 3 TE, while 8 (4.17%; 95%CI: 1.82%-8.04%) subjects showed grade 4 TBE. No episodes of grade 4 TE or ART discontinuation due to hepatotoxic events were observed. The use of ritonavir-boosted atazanavir was the only independent predictor for grade 4 TBE [adjusted odds ratio: 7.327 (95%CI: 1.417-37.89); p = 0.018] in an analysis adjusted for age, sex and baseline HIV-RNA levels, while no factor could be independently associated with grade 3-4 TE., Conclusions: Currently, the frequency of severe ART-associated TE and TBE under real-life conditions in patients with chronic viral hepatitis is similar to what has been reported previously. However, episodes of grade 4 TE are less frequent and severe TE appears to be of lesser concern.

- Abstract
Objectives: To assess the incidence of hepatitis C virus (HCV) reinfections after therapy-induced clearance in HIV-coinfected patients with prior chronic hepatitis C., Methods: Eighty-four HIV-infected subjects, who had previously achieved sustained virological response (SVR) after being treated of chronic hepatitis C, were analyzed. In all of them, at least yearly HCV RNA determinations were carried out during a median (range) of 34 (12-146) months., Results: Seventy-two (86%) subjects had been people who inject drugs (PWID), of whom 11 (15%) continued to use snorted or injected drugs during the follow-up. Four (4.76%) patients showed HCV reinfection (incidence 1.21 [95% confidence interval: 0.3-3.09] cases per 100 person-years). These patients maintained risk factors for HCV infection. In three cases, HCV genotype switched. Phylogenetic analysis of the remaining case suggested reinfection from his sexual partner., Conclusion: The incidence of HCV reinfection in the overall population of HIV-coinfected patients who achieved SVR after being treated against chronic hepatitis C is low. A low frequency of risk behavior is the main factor accounting for this modest rate of reinfection. The possibility of reinfection should not be considered a reason against treatment of HCV infection with direct acting antivirals in PWID., (Copyright © 2015 The British Infection Association.

- Abstract
Objective: Fatty liver disease (FLD) is frequently observed in HIV-infected patients and a cause of advanced liver disease. Genetic factors could play a role in determining risk for FLD development in those patients. The aim of this study was to evaluate the association of those single nucleotide polymorphisms (SNPs) previously found to be related to nonalcoholic FLD by genome-wide association analyses in the general population with the presence of FLD, including steatohepatitis, in HIV-infected individuals., Design: This is a transversal study., Methods: A total of 431 HIV-infected patients were included in this study. All of them underwent a transient elastography with the controlled attenuation parameter examination and were genotyped for 19 selected SNPs. A controlled attenuation parameter value higher than 238 dB/m was selected to define the presence of FLD. Elevated alanine aminotransferase levels and presence of FLD was considered as a surrogate marker of steatohepatitis., Results: A total of 179 (41.5%) individuals showed FLD, including 122 (28.3%) with steatohepatitis. The rs12743824 and rs738491 SNPs were independently associated with FLD and steatohepatitis, respectively. For rs12743824, among 252 individuals without FLD, 182 (72.2%) were A-allele carriers vs. 111 (62%) of 179 patients with this disease (multivariate P = 0.006; adjusted odds ratio = 0.51; 95% confidence interval = 0.33-0.83). For rs738491, 20 (16.4%) of 122 patients with steatohepatitis were TT carriers vs. 18 (5.8%) of 309 patients without this condition (multivariate P = 0.005; adjusted odds ratio = 2.94; 95% confidence interval = 1.39-6.20)., Conclusion: LPPR4 and SAMM50 allelic variants are independent risk factors for FLD and steatohepatitis development, respectively, in HIV-infected individuals.

- Abstract
Background and Aims: Clinical trials of therapy against chronic hepatitis C virus (HCV) infection including boceprevir (BOC) or telaprevir (TVR) plus pegylated interferon and ribavirin (PR) have reported considerably higher response rates than those achieved with PR alone. This study sought to evaluate the efficacy and safety of triple therapy including BOC or TVR in combination with PR in HIV/HCV-coinfected patients under real-life conditions., Methods: In a multicentre study conducted in 24 sites throughout five European countries, all HIV/HCV-coinfected patients who initiated a combination of BOC or TVR plus PR and who had at least 60 weeks of follow-up, were analyzed. Sustained virologic response 12 weeks after the scheduled end of therapy date (SVR12) and the rate of discontinuations due to adverse events (AE) were evaluated., Results: Of the 159 subjects included, 127 (79.9%) were male, 45 (34.4%) were treatment-naïve for PR and 60 (45.4%) showed cirrhosis. SVR12 was observed in 31/46 (67.4%) patients treated with BOC and 69/113 (61.1%) patients treated with TVR. Overall discontinuations due to AE rates were 8.7% for BOC and 8% for TVR. Grade 3 or 4 hematological abnormalities were frequently observed; anemia 7%, thrombocytopenia 17.2% and neutropenia 16.4%., Conclusion: The efficacy and safety of triple therapy including BOC or TVR plus PR under real-life conditions of use in the HIV/HCV-coinfected population was similar to what is observed in clinical trials. Hematological side effects are frequent but manageable.

- Abstract
Background: IL28B genotype predicts response to treatment against HCV with pegylated interferon/ribavirin (PR) and impacts on the outcome of therapy including telaprevir (TVR). This study aimed to determine the influence of the favourable IL28B genotype on early viral kinetics during therapy with TVR/PR in HIV-HCV-coinfected patients., Methods: All HIV-HCV genotype 1 coinfected subjects who received TVR/PR for at least 4 weeks were included from populations prospectively followed in 22 centres throughout Germany, Switzerland and Spain., Results: Of the 129 subjects included, 38 (29.5%) presented with IL28B genotype CC and 94 (72.9%) were treatment-experienced. A total of 96 (73.8%) patients showed undetectable plasma HCV RNA at treatment week (W)4: 30 (78.9%) of the IL28B-CC carriers and 65 (71.4%) of the non-CC carriers (P=0.377). Among treatment-naive patients, proportions of undetectable HCV RNA among IL28B-CC versus non-CC carriers were 8/9 (88.9%) versus 3/9 (33.3%; P=0.016) and 14/17 (82.4%) versus 11/18 (61.1%; P=0.164) at W2 and W4. The decrease of HCV RNA at W2 and W4 was similar among the IL28B carriers., Conclusions: IL28B genotype does not predict W4 response to TVR/PR in HIV-HCV-coinfected patients, regardless of their treatment history. However, there is evidence of an impact on response during the first weeks in treatment-naive patients.
